First of all, thanks for the compliments for the music. I didn't have much time and chose to keep it very simple, but I'm glad you liked it. Now, speaking about the puzzle, you're not the only one who struggled trying solving it. I remember losing 45 minutes with a similiar puzzle in Resident Evil 4, so I understand your pain. We'll update the game in the future and will find a way to make puzzles less frustrating. Thank you for your kind words.
